No. Eligibility for TD turns on the relationship, a spouse or an unmarried child under 21, not on the principal's academic detail. A spouse's own degrees have no bearing on TD, which permits study but does not authorize employment of any kind.
Keep the dependent file about relationship, not qualifications
Keep the dependent evidence focused on the qualifying relationship, identity and applicable status requirements. TD permits study but does not authorize employment; the spouse’s degree does not change that. Seeking information about a future job is different from performing work. Obtain specific advice before any employment, remote activity or unpaid placement rather than assuming the academic records create permission.
TD does not authorize employment, and work performed on U.S. soil for a Canadian employer is still work in the United States. A school admission offer can extend beyond a child’s eligibility for TD. Ask counsel to look at every family member's record, not only the principal's, and keep in mind that TD permits study but does not authorise work of any kind. An eligible spouse or unmarried child under 21 may seek TD, but a spouse's own work plans need a separate route or authorization analysis.
Speak with the office responsible for international students about documents and deadlines for a possible independent study route.
